Subject[PATCH V4 6/6] ARM: OMAP3+: use cpu0-cpufreq driver in device tree supported boot
Date
With OMAP3+ and AM33xx supported SoC having defined CPU device tree
entries with operating-points and clock nodes defined, we can now use
the SoC generic cpufreq-cpu0 driver by registering appropriate device.

Introduced as a result of alignment in http://marc.info/?t=136450773400004&r=1&w=2
previous versions do not use this approach.

This would probably be good to get merged *after* Rafael's tree is merged in.

[Probably belongs to Kevin/Tony's tree?]
